CVE-2012-0841
libxml2 before 2.8.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data.
Does this matter?
Lower severity and a low EPSS score (3.26%). Track it; it rarely justifies an emergency change on its own.
